6 Claims. (Cl. 29481) This invention relates to a hoist lift bail and particularly to a bail to be applied to hand-vehicles such as handtrucks or wheelbarrows so that the same may be lifted in loaded or unloaded condition from the ground onto scaffolding such as the type of scaffolding used to construct buildings.

In the construction of buildings and other walls it is customary to provide sectionalized scaffolding adjacent to the wall and to utilize preconstructed sections to raise the scaffolding as it is desired. Heretofore considerable difficulty has been experienced in producing on the scaffolding the mortar, bricks and other building materials desired to construct the wall. Heretofore, it has been customary either for the workmen on the platform to drop a rope and lift the items by manual power or to provide derricks or winches on the platforms and lift the material to the various sections usually by workmen on the platform. Recently, it has been proposed to provide a run ning line along the top of the sectionalized scaffold and to drop a bight from the running line to the ground with a suitable work engaging finger to lift pails, tongs or other items to the platform on the scaffold by means of a donkey engine on the ground.

The present invention provides a method by which a hand vehicle such as a truck or wheelbarrow may be conveniently attached to the aforenoted running line and lifted bodily up to the scaffolding so that workmen on the platform may remove the load therefrom without the utilization of intermediate carriers such as tongs or buckets to convey the material upward. Further, this construction not only saves the time of unloading the wheelbarrow or other vehicle and placing the material in containers which may be readily lifted by the fingers but also allows the lifting of a considerably greater load at the same time.

This is accomplished by means of providing a bail ring on the forward end of the vehicle and to provide links having rings adapted to slide over the usual handles of such vehicles and a bail rod on which the links are journaled and having an end adapted to extend through the ring on the forward end of the vehicle so that when the bail rod is in position it will provide a bail extending longitudinally over the vehicle and attached thereto so that the ordinary lifting fingers or lifting hook of the running line may be utilized to connect the running line to the vehicle so that the vehicle may be readily lifted onto the scafiold structure.

It is accordingly an object of the invention to provide an improved bail lift.

It is a further object of the invention to provide a bail which may be readily attached to a hand operated vehicle.

It is a further object of the invention to provide a bail which may be readily connected to any type of hook.

It is a further object of the invention to provide a bail which may be readily attached or detached to various types of hand-vehicles so that the same may be raised to a scaffold.

Other objects and many of the attendant advantages of 2,718,425 Patented Sept. 20, 1955 the present invention will be apparent from the following detailed description taken in conjunction with the accompanying drawing in which:

In the exemplary embodiment according to the invention a scaffold indicated generally at 10 is provided of a plurality of sections 12 which as is well known may be stacked one on top of the other with suitable interfitting connections and arranged in spaced relation by means of suitable space braces 14. A workmans platform 16 is constructed of suitable planks and a material receiving platform 18 is likewise constructed of suitable planks or other longitudinal stringer material.

A running line 20 is mounted on suitable pulleys 22 mounted on pulley brackets 24 which are preferably of the type shown in my co-pending application, Serial No. 334,908, filed February 3, 1953.

A lifting grapple 26 is provided with a pulley 28 for mounting on the running line 2!) and is preferably of the type shown in my copending application, Serial No. 334,908, filed February 3, 1953. The grapple 26 is provided with a plurality of depending fingers 30 having longitudinally or laterally extending portions 32 arranged in substantially linear formation. The laterally extending fingers 32 arranged in substantially linear formation make a very firm support for connection with the bail presently to be described. However, the bail presently to be described is also provided with means for connection to a single hook so that any type of running line and connection may be used.

The hoist bail proper consists of a ring 36 which may be connected to the front end of the vehicle in any suitable manner, herein shown as having a bracket including depending legs 38 and 40 which extend downwardly along the squared end portion of the usual masons barrow 42 and have inturned portions 44 and 46 interlocking with the usual handle side members 48 and 50. The masons barrow is provided with the usual rectangular end 52 having reinforcing brackets 54 and 56. The depending bracket portions 33 and 40 are connected to the reinforcing members 54 and 56 by suitable fasteners such as the bolts 60 so that the ring 36 is rigidly mounted in spaced relation to the forward end of the hand vehicle and preferably of such height so that the usual load of brick, water pails or other such items may be readily deposited thereunder. The bail rod 62 has an end portion 64 adapted to extend through the ring 36 while the opposite end 66 has attached thereto a pair of links 68 and 70 so that the links 68 and 70 are free to swing or be journaled on the end of the rod 62. The lower end of the rods 68 and 70 are provided with rings 72 and 74 adapted to slide over the handles 76 of the hand vehicle. The end 64 is provided with an aperture 78 for receiving a suitable fastener such as a nail 80.

In certain instances it is desirable to maintain the rod 62 in a predetermined relation and in such cases the ring 36 will be provided with apertures 82 to correspond with the aperture 78 so that the nail or other fastener may extend through the apertures 82 and 78 to retain the rod 62 in predetermined relation to the ring 36.

Instead of providing a ring 36 and the rod 62 with the apertures 78 and 82 in alignment with each other, the end 64 of the rod 62 may be constructed with a shape other than round, such as square, while the ring 36 may be provided with a similar opening so that the rodmay be inserted thereinto and be non-rotatably received therein. I

In order to prevent undue ffexing of the rod 62 a re inforcing rod 86 may be connected thereto by any suitable means such as welding and strut members 88 and 90 may be attached thereto and an intermediate strut member 92 may be welded between the central portions of the rod 86 and the central portion of the bail 62 and preferably an aperture 94 is provided in the strut member 92 so that a single hook member may be attached through the opening 94 to lift the bail rod and any vehicle attached thereto.

When the bail ring 96 is attached to another type of vehicle such as the bed-type Wheelbarrow 98 bracket members 180 and 102 may be provided with suitable brace members 164 and 106 so that the ring 96 may be conveniently attached to the forward end of the bed portion of the barrow 98 and suitable feet members 108 and 110 may be attached thereto preferably by turning up the ends of the brackets 100 and 102 so that the bracket may be readily attached to the hand rails or handles 112. The rings 72 and 74 of the links 68 and 71) will engage the handles 114 of this type of barrow in the same manner as they were attached to the handles 76 of the barrow of the masons type.

Obviously, the rings 36 and '96 may be attached on any type of vehicle regardless of the number of front wheels so long as it is provided with a ground engaging structure at the forward end and a pair of spaced apart rigidly mounted control handles at the opposite end.

In the operation of the lifting bail according to the construction the various vehicles to be lifted will be provided with suitable lifting rings or bail rings 36 or 96. The bail rods 62 will be provided with the rings 72 and 74 of suflicient size to extend over the various type of vehicle handles 76 or 114. Preferably, a bail is provided for each vehicle to be used on the hoist, in which event, the bail rod 62 may be permanently mounted on the vehicles. However, it is obvious that the bail rod 62 may be applied to the vehicles only during the hoisting operation, in which case they will be detachably connected and used on the vehicles as they are to be hoisted. When the finger-type lift is used, obviously, the fingers will be distributed along the bail rod 62 so that there will be little bending stress therein and the strut or truss member will probably be unnecessary. However, when a single hook is used it is believed that the truss member will be desirable.

While for purposes of exemplification a presently preferred embodiment of the invention has been shown and described according to the best present understanding thereof. It will be apparent to those skilled in the art that changes and modifications may be made in the con- 4 struction and arrangement of the parts thereof without departing from the true spirit of the invention.
